Prop Firm Drawdown Calculator
Enter the values from your exact account. The calculator shows the current loss floor and how much equity remains before a breach.
Current result
A static floor stays at starting balance minus the maximum loss amount.
Use this calculator for a TradeDay account
- Choose EOD trailing, locks at starting balance for a current TradeDay EOD route, or Intraday trailing for an intraday route.
- Copy the starting balance and maximum drawdown from the current table for the exact route and size.
- For EOD, enter the highest end-of-day balance used by TradeDay. For intraday, enter the highest tracked balance or equity named by the account rule.
- Use current equity for the remaining-buffer result. The active floor is enforced during the session even when the trail updates at end of day.

Which high-water value should you enter?
- Intraday trailing: the highest equity or balance specified by the firm, including an intraday peak when the rule tracks it.
- EOD trailing: the highest end-of-day balance used by the firm after its daily calculation.
- Static: the high-water value does not move the floor.
Check the rule before using the result
Firms differ on balance versus equity, end-of-day timing, lock points, commissions, open losses, resets, and account stage. Copy those inputs from the current rule for your exact product.
